The 11.0.20 update has seem to introduce an issue with alt + dragging midi notes to duplicate them. Normally you can left click/hold, alt, and then drag a duplicate of the midi note, but since updating this behavior is really hit and miss and I have to drag the note to a different position before hitting alt for it to 100% create a duplicate. This is a pretty annoying bug and would appreciate if it could be fixed in the next maintenance update!
This is known and already reported issue. Thank you.
Same here. Sometimes it works and sometimes it doesn’t. If you find that it doesn’t work as expected, press alt (a scissor tool will appear, ignore) then click on the note and drag it. I find that I am using the normal click/alt and the alt/click about 50/50. And yes, it is a pain in the butt having to constantly be watching out for this erratic behavior. This work around only works in key edit and not drum.
